Barriers to International Trade: Tariffs, Quotas and Non-Tariff Measures
Quick Answer
Trade barriers are government-imposed restrictions on international trade. They include tariffs, import quotas, subsidies, and regulatory measures that protect domestic industries while reducing the efficiency of global trade.
What Are Trade Barriers?
Trade barriers are government policies, regulations, or practices that restrict the free flow of goods and services between countries. While they are often justified on grounds of protecting domestic industries, national security, or public health, economists generally regard most trade barriers as economically inefficient — benefiting protected industries at the expense of consumers and the broader economy.
Understanding trade barriers is fundamental to understanding international trade, trade policy negotiations, and the work of organizations like the World Trade Organization (WTO).
Types of Trade Barriers
1. Tariffs
A tariff is a tax imposed by a government on imported goods. It raises the price of foreign products in the domestic market, making them less competitive relative to domestically produced goods.
- Ad valorem tariff: A percentage of the imported good's value (e.g., 10% of the invoice price)
- Specific tariff: A fixed charge per unit of quantity (e.g., $5 per kilogram)
Tariff revenues accrue to the government, but higher prices are paid by domestic consumers. Industries dependent on imported inputs also face higher costs.
2. Import Quotas
A quota limits the quantity of a specific good that can be imported within a given period. Unlike tariffs, quotas generate no government revenue — instead, the benefit of the price increase accrues to those holding the import licenses.
3. Export Subsidies
Governments subsidize domestic producers to give them an artificial price advantage in export markets. Export subsidies distort global competition and are heavily regulated by WTO rules.
4. Non-Tariff Barriers (NTBs)
Non-tariff barriers are regulatory and administrative measures that restrict trade without being explicit tariffs or quotas:
- Technical standards and regulations: Different product standards create compliance costs for exporters
- Sanitary and phytosanitary measures: Food safety and plant/animal health standards
- Customs procedures: Complex documentation or slow border processing
- Local content requirements: Mandating minimum proportions of domestically produced inputs
- Government procurement policies favoring domestic suppliers
Arguments For and Against Trade Barriers
| Arguments For | Arguments Against |
|---|---|
| Protect infant industries in developing countries | Raise consumer prices and reduce choice |
| Safeguard national security (strategic industries) | Inefficient — protect uncompetitive industries |
| Retaliate against unfair foreign practices (dumping) | Invite retaliation, reducing overall trade |
| Protect jobs in import-competing sectors | Higher import costs hurt other industries |
